SURFACE-TREATING DEVICE.

Application filed November 16, 1922.

To all whom. it may concern:

Be it known that I, LEON P. WILSON, a citizen of the United States, and a resident of Sioux City, in the county of WVoodbury and State of Iowa, have invented certain new and useful Improvements in Surface- Treating Devices, of which the following is a specification.

My present invention aims, broadly, to provide an improved set of surface treating devices, as for example, window brushes, scrub brushes, dust mops, floor mops or other handled devices for treating or working upon surfaces and having a handle which may be used interchangeably with and de tachably secured to said devices.

The invention has for a further object the production of an improved flexible back mop having a supporting frame provided with a handle and adapted to be removably secured to the mop and also adapted for use with a window brush or scrub brush or other surface treating device having a rigid back.

Furthermore, the invention has for an object the production of a surface treating device having a handle so pivoted thereto as to permit relative oscillation between the device and the handle and yet normally hold the device and handle yieldably in determinate relative positions.

Still another object of the invention is the production of an improved surface treating device which is comparatively inexpensive and simple in construction yet stable and thoroughly efficient in operation.

The above and other objects and advantages I successfully attain in the embodiments hereinafter described, defined in the appended claims and illustrated in the ac companying drawings which form a part of this application and in which like characters of reference indicate corresponding parts through the several views, of which,-

Fig. 1 is a plan of my invention as embodied in a window brush.

Fig. 2 is a side elevation of the same as applying water to a window.

Fig. 3 is a side elevation of the same as used for drying the window.

Fig. 4: is a plan of the device as embodied in a flexible dust mop, and

Fig. 5 is an enlarged transverse section of the same taken on the line 55 of Fig. 4.

Referring, now, more particularly to Sheet 1 of the drawings, I provide a frame of wire, preferably rectangular in general Serial No. 601,239.

contour and consisting of a single piece and formed with substantially parallel front and rear members, 6, and inwardly bent U-shaped side members, the arms, 7 of which are inclined in the direction of their junctures with the member, 6. The webs, 8, of said side members are formed with vertically disposed eyes, 9, formed with their transverse axes disposed oppositely to each other and at slight angles to the transverse axis of the frame, to which eyes the handle is so pivoted as to permit relative oscillation between the frame and handle and normally hold the frame and handle yieldably in substantially parallel planes. In the present embodiment the handle proper, 10, is provided with diverging tangs, 11, having their free end portions, 12, bent inwardly toward each other and formed with hooks, 13', in serted within the eyes, 9. The said tangs are of spring material and are so spaced and related to the eyes, 9, as to permit relative oscillation between the frame and the handle and yet coact with the eyes to normally hold the handle and frame yieldably retracted in substantial parallel planes, as will be understood from Fig. 3. The brush illustrated comprises a rigid flat back, 14, provided on one side with bristles, 15, and on its opposite or upper side adjacent the front edge with a suitable form of squilgee.

The wire supporting frame rests flatly on the upper side of the back, 14, and is removably secured thereto preferably by means including flanges, 17 disposed in parallelism with the arms, 7, of one of the U-shaped side frame members, and suitably secured to the back, 14, to engage, respectively, the adjacent sides of said arms, the flanges being formed with horizontally projecting parts, 18, which engage the upper sides of said arms. Between the arms, 7, of the other U-shaped frame member are flanges, 19, also mounted on the back, 14, and positioned in parallelism and engageable with the adjacent sides of the said latter arms, 7, and between said arms is pivoted a button, 20, adapted to extend across and engage the upper sides of the said arms, 7.

It will now be evident that when thus mounted the frame and brush are secure against accidental relative displacement. To separate the frame and brush it is only necessary to turn the button, 20, to the position indicated in dotted lines in Fig. 1, whereupon the adjacent side of the wire frame may be lifted from the flanges, 19, and then removed from the opposite securing elements, 17-18 by sliding the frame in the direction of the flanges, 19. It is thought the operation of replacement of the frame and brush is obvious.

Fig. 2 shows the device as applying the brush to a window, the handle being swung at a slight angle to the plane of the brush and in this position, when the brush or handle are released, the eyes, 9, of the frame coact with the tangs of the handle to restore the brush and handle to the relative positions shown in Fig. 3 with the tangs, 11, in engagement with the adjacent frame member, 6, in which position the squilgee, 16, is applied to the window.

In Figs. at and 5 I present a mop includ ing a back, 21., consisting of a sheet of fabric or other suitable flexible sheet, to the under side of which are suitably secured the thrums, 22. Above the back, 21, is a second sheet of fabric or other suitable flexible material, 23, divided, as at 24, on the longitudinal, median line of the back in two parts having their remote side and end edges suitably secured to the corresponding edges of the sheet, 21. In the embodiment illustrated the thrums comprise rows of looped yarn or cotton cord having the high-ts of the loops stitched to the said sheet, 21, the outermost loops being stitched together with the adjacent edges of the sheets, 21 and 23, as at 25. The wire frame, above described, is inserted through the opening, 24, between the sheets 21 and 23, the intermediate portion of the adjacent edges of the upper sheet, 23, being cut out longitudinally as at 26 to permit the sheet, 23, to properly fit around the lower portions of the eyes, 9. On the remote sides of the eyes, 9, the adjacent edges of the divided sheet, 23, are provided with eyelets, 27 through which are respectively extended tapes, 28, suitably secured, as at 29, to the back, 21, whereby the frame is secured to the mop by tying the mated tapes together, as indicated at 30, in Fig. 4.

\Vhile I have illustrated the preferred embodiments of the device, I would not he understood as being limited to such specific construction, for various alterations and modifications may be made in the details of construction and arrangements of parts without departing from the spirit and scope of the invention as defined in the following 1,

claims, to-wit:

1. A device of the class describe-d comprising a surface treating element having a flat back, a handle, eyes on the back, and

tangs on the handle pivoted in the eyes to,

permit relative oscillation between the back and handle, the eyes being disposed in vertical planes at an angle to the vertical plane of the handle, and the tangs having parts coacting with the eyes to normally hold the back and handle yieldably in determinate relative positions.

A handle attachment for surface treating devices including a wire supporting frame having parallel front and rear members and inwardly extending V-shaped side members connected at their outer ends with said front and rear members to form loops and having their inner portions formed with eyes, a handle having tangs receivable in said eyes, said frame serving as a support receivable within a hollow-backed flexible fabric brush or attachable to the top of a stiff-backed brush.

In testimony whereof, I have hereunto set my hand this 11th day of November,

LEON P. IWILSON.
